i think it would be ... 60 because 30 times 2 = 60 and on each page there are 2 pages the one in the front and the one in the back .... I hoped i gaved u the right answer
when you number something it depends wethor or not you are using 0 as a place holder (01 02 03 ect.) if so the answer would be 60 because all you have to do is multiply by two. If you are not using place holders the answer would be 59 because 30*2=60-9 you take away 9 beace there were nine place holders (Zero)
